It can't be read > direct via javascript? No, access to the registry is hopefully impossible via browser-side JavaScript (otherwise that would be a security hole, IMHO). However, it might not be necessary to "run something" on the desktop; in the simplest case an appropriate shortcut to "start" the web application might suffice. If the value of the environment variable COMPUTERNAME would be okay, it is as simple as: http://www.example.com/computername=%COMPUTERNAME% (See <http://stackoverflow.com/questions/21315708/reading-environment-variables-with-javascript>.) If you really need to send the value of a registry key, a small batch script should do the trick. -- Christoph M.
